SI Units Explained: The Foundation of Physics

Before you can convert anything between units, you need to understand what SI units actually are and why they exist. This video covers the foundation: the seven SI base units (meter, kilogram, second, ampere, kelvin, mole, candela), how derived units like the newton and joule are built directly from those seven, and why mixing up units in the real world has caused actual disasters (NASA lost a Mars orbiter in 1999 over exactly this).

Covers: what SI units are, the seven base units, derived units (force, energy, power, pressure, charge, frequency), and how to tell a base unit from a derived one.

Part 2 covers actual unit conversion methods. Full practice problems with worked solutions at AUX.
